The EU boar taint study – Spring 2009 

1. Introduction 

The aim of  this study was  to gain  insight  into consumer acceptance of and attitude  towards 

castration  and  boar  taint  and  the  potential  impact  of  this  acceptance  and  attitude  on  the 

purchasing behaviour of pork of the European consumer.  

A  controlled  approach  is  chosen  that  resembles  the  real  situation  as  good  as  possible. 

Therefore attitudes without  conditioning and after  conditioning will be measured and meat 

will be tested that is eaten in almost every country. Chosen is to use loin, directly after the ribs. 

In order to get these insight consumers will be subjected to the following research approach: 

• Pre‐test in which attitude will be measured towards castration 

• Sensory  test  in which  consumers  are  rating  three  types  of meat:  detection  +  (boar 

meat with boar taint), detection – (boar meat without boar taint) and gilt meat 

• A kitchen session in which detection + meat is cooked 

• Post‐test in which the attitude towards castration is measured again. 

All consumers have to do all steps in the research project. 

As a result, the study will provide quantitative information on: 

• the attitude of consumers towards boar taint before tasting it and after tasting it. 

• a sensory evaluation of meat with and without boar taint in relation to: 

□ the purchasing behaviour of European consumers with regard to pork; 

□ the  perception/attitude  regarding  two  types  of  boar  meat:  detection+  and 

detection–; 

□ perceptions/attitudes towards castration; 

□ purchasing and utilisation intentions in Europe. 

  

The focus of the study  is on obtaining useful  information that can be applied  in practice. The 

results of the study should make  it possible to determine the attitude of consumers towards 

castration and boar taint and to what degree consumers accept boar taint and whether there 

is any difference between consumer acceptance of pork from boars and gilts. 

D131/D132 – 1

In paragraph 2 the detailed protocol  for the consumer research  is presented.  In paragraph 3 

the  sample  of  consumers will  be  described.  In  paragraph  4  the  sample  of  animals will  be 

described and in chapter 5 the cooking protocol will be described. 

2. Detailed approach consumer research 

All consumers will have to follow the total procedure from phase 1 to 4.  

Phase 1: Pre‐test on attitudes towards boar taint (30 minutes) 

In this phase consumers are asked to fill in a questionnaire with the following subjects: 

• purchasing behaviour with regard to pork 

• factors for purchasing 

• acceptance of castration 

• perception 

• attitudes regarding meat quality 

• life style 

• socio‐demographic factors 

The questionnaire of the pre‐test is presented in Appendix 1. 

Phase 2: Sensory  test  in which meat with boar  taint and without boar  taint  is submitted  for 

evaluation (30 minutes) 

In this phase, blade pork chops loin of 3 types: 

• boar meat detection+ 

• boar meat detection– and  

• gilt meat 

They are submitted and evaluated in terms in general, on taste, odour and mouth feeling. 

The order of presentation will be randomised. 

The consumers  sit  in a  sensory perception area, each  in his or her  individual cabin, and are 

given  3  different  pieces  of  meat  via  a  hatch,  each  of  which  they  are  asked  to  evaluate 

separately.  If  it  is not possible to do this  in cabins, consumers have to be on separate tables, 

and the testing has to be completely silent.  

Appendix 2. Contains the list of questions they answer for each piece of meat. 

D131/D132 – 2

ALCASDE, 2009 D.1.3.1 & D.1.3.2

Phase 3: kitchen session during which detection+ meat is prepared (10 minutes) 

The respondents are taken into a kitchen where detection+ is being prepared. Two samples of 

two animals have to be prepared. They are not allowed to make any comments while they are 

evaluating  the odour of  the meat  and  looking  at  it.  They  are  then  asked  to  return  to  their 

individual  cabins  and  complete  a questionnaire  in which  the  respondents  are  asked  to  give 

their opinion regarding the meat that was being prepared and to explain what they would do if 

they were at home preparing the same kind of meat (Appendix IV.III.).  

Phase 4: Post‐questionnaire (20 minutes) 

In  this  phase  a  part  of  the  pre‐test  questionnaire  is  done  again  (Appendix  4.),  added with 

opinion questions about castration, attitudes towards animal welfare and about boar taint  in 

meat and meat products. 

Database  

All results from phase 1 to 4 and the lab results on androstenone, skatole and indole results of 

the meat have to be connected on respondent level. A data entry model will be presented in a 

later stage. 

3. Sample survey of consumers 

For this study, a group of consumers  is selected which  is representative for the society  in the 

research  country  as  a  whole  in  order  to  enable  practical  extrapolation  of  the  results.  

Representativeness has to be reached on: 

• age 

• types of household 

• gender 

• buying location of the meat (supermarket/specialty shop/others) 

• household income 

• employment at household level 

 The aim has to be to realise a 50:50 ratio between men and women. However, as men are less 

sensitive, in terms of their ability to detect the odour of boar taint, a slight overrepresentation 

of women is considered acceptable. Although the percentage of men has tried to be equal at 

least 25% of the overall sample. 

D131/D132 – 3

The  research has  to be done  in an urban and a more  suburban environment,  if possible.  In 

each environment at least 50 respondents have to be reached. 

All of the respondents must eat pork at least once a month, have to be (partly) responsible for 

cooking in their household and (partly) responsible for the groceries in their household. 

The sample consisted of 130 consumers per country, who are subjected to a complete series of 

tests as follows: 

• pre‐test questionnaire; 

• a sensory test; 

• a kitchen session; 

• post‐test questionnaire. 

4. Animal/meat sampling 

The  boar meat  used  for  the  sensory  investigation must  come  from  farms where  the male 

animals are not castrated.  

The meat must be from conventional crossing (genetics) in the test country. This means that if 

possible local meat has to be used. This type of meat comes from animals in a weight category 

which  is  in  line with  the weight of  animals  commonly  slaughtered  in  [country of  test],  and 

there  are  enough  of  these  animals  in  stock  that  have  not  been  castrated  from  a  sufficient 

number of farms. In case foreign meat is used, there has to be a good reason for doing so.  

For  the  Italian  market,  with  a  self  sufficiency  of  59%,  French  meat  is  used  since  that  is 

commonly  in  the  Italian  fresh  meat  market.  The  typical  Italian  meat  is  mainly  used  for 

processed products and the age of the males  is much higher than would be normal for fresh 

meat. In the UK Spanish meat is used. 

In all other markets (Spain, France, the Netherlands and Germany) local meat is used. 

As  all  the meat  is  commercially  available,  it  can  be  bought  from  a  slaughterhouse  or  be 

controlled slaughtered.  If meat from a slaughterhouse  is used, at  least the cutting procedure 

has to be as described in Appendix 5. (Slaughterhouse protocol at IRTA). The selected animals 

have a carcass weight and classification as common in the country for fresh meat. 

In order to obtain sufficient statistical variation at supply side, at least 20 boars detection+, 20 

boars detection– and 20 gilts have  to be used  in each country. This corresponded 1 roast of 

meat per animal. The roast will be divided in slice which has a thickness of at least 0.5 cm. The 

D131/D132 – 4

ALCASDE, 2009 D.1.3.1 & D.1.3.2

skin need to be taking off of the roast sample. A minimum of 0.5 cm of external fat needs to be 

preserved on the slice of meat before cooking. 

 

The meat has to be collected over a period of 2 to 4 weeks to ensure sufficient variation over 

the various farms. The meat must come from at least 3 farms. 

A normal loin is divided in two for the test, so that samples as shown result. 

 

Method for selecting meat samples: 

In the slaughterhouse, animals were carved up which met the requirements described above. 

The remaining detection+ pieces are used for the kitchen session (phase 2). 

For  the  study, meat was  used  from  boars  detection+,  boars  detection–  and  gilts.  The  boar 

meat used for the sensory investigation must come from:  

• farms where the animals are not castrated; 

• animals which are representative of what is normally available in the supermarket, i.e. 

within the usual weight class and quality available in retail outlets;  

• as many farms as practically possible in order to ensure as much diversity as possible in 

the supply. 

D131/D132 – 5

Whether meat is detection + will be determined by testing neck fat samples. Whether meat is 

detection + will be determined by  testing concentration of androstenone and  scatol  level  in 

the fat samples. Human testing was proposed first, but could not be equalized between four 

countries of origin. 

The borders of detection + boar meat are: 

a) Androstenone > 1 µg/g melted fat 

b) Skatole > 0.2 µg/g melted fat 

c) Androstenone > 0.5 µg/g melted fat and skatole > 0.15 µg/g melted fat 

The borders of detection –boar meat are: 

a) Androstenone < 0.5 µg/g melted fat and skatole < 0.15 µg/g melted fat 

These borders will be checked with experts, by everybody.  

Working procedure at the slaughterhouse  

As  soon  as  the  animals  are  transported  from  the  storage  area  to  the  carving  area  the 

slaughterhouse hook number  is noted and researchers present check whether the meat  is of 

the correct type.  

No more than a single animal would be present  in the carving area. For each slaughterhouse 

hook number used, the UBN number and the earmark number are also checked. This  is done 

for the next carving day. 

All of the meat carved out is labelled according to the following codes:

ALCASDE, 2009 D.1.3.1 & D.1.3.2

The codes are built as follows: 

• Country telephone code 

• Date of slaughtering period 

• Number of carcass 

Neck 

A fat sample  is cut from the neck, and the samples are supplied to a laboratory at the end of 

the carving period. These samples are used to determine the concentrations of androstenone, 

indole and skatole in the meat. 

Blade pork chops  

• from each animal, a number of blade pork chops are carved out; 

• all the blade pork chops have a similar thickness; 

• per animal, the test pieces are separately packed in the deep freeze bags provided and 

stickered with the code number described above;  

• the researchers present will help with the packaging and sorting for distribution. 

5. Cooking protocol 

The  meat  is  cooked  to  ensure  food  safety  is  guaranteed  and  the  protocol  is  followed 

professionally. 

Oil: Maïs‐oil (oil with the less smell) 

Cooking plate (with a straight surface) of: ± 180°C 

Cut the meat pieces in two samples, which are of equal size.  

Start  cooking  with  “x”  minutes  on  one  side  and  “x”  minutes  on  the  other  side.  Change 

regularly. The meat is ready as the inside temperature is at least 80°C. 

 

The meat is salted after cooking with 1 gram salt per 200 gram meat.

Statements (1- Strongly disagree 9- Strongly agree)

I don’t know= Do not answer

Transportation conditions of male piglets could affect sensory quality of pig meat

I would like to see that meat from castrated pigs is labeled

High feed quality of male piglets improves sensory quality of pigmeat

It is acceptable that pig meat from non-castrated pigs is more expensive than the castrated one

Castration of male piglets is justified because it improves sensory quality of pig meat (taste and odor)

I think pig males should not be castrated, because I believe that we should not change the state of the animal

Castration of male pig is so painful that I think it shouldn’t be done

Previous studies indicate that individuals in general respond to surveys differently from the way they act in real life. It is quite common to find that individuals say they are willing to pay higher prices than those that they are really willing to pay. We believe that this is due to the difficulty in calculating the exact impact of these higher expenses on the household economy. It is easy to be generous when in reality one does not need to pay more in the shop.

Moreover, it is not necessary to identify yourself or give us information that you don’t need to do. Thank you in advance for your invaluable contribution to our investigation. Date: ____________________

28. Please indicate the degree to which you agree or disagree with each of the following statements about pig castration

Statements (1- Strongly disagree 9- Strongly agree)

I don’t know= Do not answer

Transportation conditions of male piglets could affect sensory quality of pig meat

I would like to see that meat from castrated pigs is labeled

High feed quality of male piglets improves sensory quality of pigmeat

It is acceptable that pig meat from non-castrated pigs is more expensive than the castrated one

Castration of male piglets is justified because it improves sensory quality of pig meat (taste and odor)

I think pig males should not be castrated, because I believe that we should not change the state of the animal

Castration of male pig is so painful that I think it shouldn’t be done

29. Considering the following options, which one do you consider as the most appropriate technique to apply? Please rank them from the MOST (1) appropriate to the LESS (5) appropriate.

Castration Types Rank

Castration without anesthesia:

Castration with anesthesia

Immunocastration

Entire pigs

Females

30. Do you know which of the previous method of pig castration is the most used in Country of research? Yes: which one?.......................................................... No

31. Are you familiar with the relationship between castration and boar taint? Yes No

D131/D132 – 25

32. In your opinion what is the relationship between castration methods, animal welfare and boar taint. (1= no effect to 9= high effect)

Castration methods Animal welfare Boar taint presence

Castration without anesthesia

Castration with anesthesia

Immunocastration

Entire pigs

Females

33. If you buy fresh pork meat with boar taint in some place, are you going to buy pork in that place again? Yes No

Previous studies indicate that individuals in general respond to surveys differently from the way they act in real life. It is quite common to find that individuals say they are willing to pay higher prices than those that they are really willing to pay. We believe that this is due to the difficulty in calculating the exact impact of these higher expenses on the household economy. It is easy to be generous when in reality one does not need to pay more in the shop.

34. ENSURING SENSORIAL QUALITY (taste and odor) of fresh pork meat from entire pig (non-castrated) implies higher costs to farmers as some controls have to be undertaken in order to remove products with unpleasant smell from the fresh meat chain. Taking into account that in Country of research the average price of pork loan is 7€/Kg, how much MORE you would be willing to pay for the pork meat to guarantee sensorial quality? €/kg (Choose from the list below)

0 0.25 0.50 0.75 1 1.25 1.5 1.75 2 2.25 2.50 2.75 3

35. You'll find a series of cards. Can you tell me in each one, which is your favorite product? (to be randomized)
